Mexico’s most Challenging Long Distance Triathlon.

Welcome to Mexico’s most challenging long distance triathlon (113km), set on the beautiful Residential San Gil, in its private lake and then a really nice uphill to Huimilpan an Amealco towns in the mountain backdrop of Queretaro, Mexico.

Described by athletes as one of the toughest bike courses in Mexico´s triathlon calendar, Challenge San Gil is a favorite to Mexican triathletes, and we hope that it will become a favorite to international athletes. The physical and mental challenges will push athletes to their limits but the enthusiasm, warmth, and welcome of the local supporters are second to none with the resulting atmosphere for getting even the most tired competitor across the line.


Challenge San Gil will host a multi-day triathlon festival that celebrates the world’s #1 fastest-growing sport and the world Triathlon best series of Challenge Family.

The weather in San Gil in June and July is great, as an average day is 27-32 C with clear blue skies and light winds. It is, however, the start of the raining season in Central Mexico, so athletes must be prepared for all eventualities.

2018 Athletes Guide will be available soon, the actual published Guide is from the 2017 event guide.
